BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to waste collection devices. More specifically, the present invention provides a pet waste disposal apparatus having an elongated shaft having a handle at a first end thereof and a base at a second end thereof, wherein a removable cartridge with a plurality of tines for impaling waste is removably securable to said base of said disposal apparatus. In this way, the cartridge can be disposed of after it has been used to collect pet waste thereon.

Cleaning pet waste can be an arduous and unsanitary task. Most pet owners often resort to carrying around small plastic bags in order to manually pick up and dispose of pet waste. This can be quite unsanitary and can cause feces and other debris to contact the hands or clothing of the pet owner. Some pet owners may use devices that can pick up pet waste in a shovel-like manner, however these devices need to be cleaned of pet waste after every use which can be undesirable and impractical. Further, it can be difficult to pick up pet waste using a scooping motion, preventing the pet owner from being able to clean up all of the pet waste. Thus, a device for allowing user to more easily collect pet waste without having to contact the pet waste with his or her hands is desired.

Description of the Prior Art

Devices have been disclosed in the prior art that relate to pet waste disposal apparatuses. These include devices that have been patented and published in patent application publications. These devices generally relate to pet waste disposal devices for scooping pet waste from the ground. These prior art devices have several known drawbacks. Some devices include claw-like structures for picking up pet waste and disposing of it thereafter. However, these devices are intended to be reused and can become quite dirty and unsanitary. Further, the claw-like portion requires daily cleaning and sanitizing as pet waste becomes stuck thereon. Other devices provide spike-like structures for impaling pet waste; however it becomes difficult to remove the pet waste from the spikes and requires manual removal of the pet waste from the spikes in order to later reuse the device.

Thus, there exists a need for a new and improved pet waste disposal apparatus having an elongated and adjustable handle and a base to which disposable cartridges with a plurality of tines can be removably attached. In light of the devices disclosed in the prior art, it is submitted that the present invention substantially diverges in design elements from the prior art and consequently it is clear that there is a need in the art for an improvement to existing pet waste disposal devices. In this regard the instant invention substantially fulfills these needs.

Further, the ring 13 can be clipped to the user's belt or other support for easy carrying of the pet waste disposal device.

The second end of the elongated shaft 14 comprises a base 16, wherein the base 16 includes a plate 17, wherein the plate 17 is substantially planar in structure and is rectangular shaped in a preferred embodiment. The base 16 further provides a well on a central portion of the plate 17 having an open end and an interior volume, wherein the open end is flush with the second side of the plate 17.

A cartridge 18 is removably securable to the base 16 of the pet waste disposal apparatus 11. The cartridge 18 comprises a first side having a nub 20 thereon and a second side having a plurality of tines 19 extending therefrom. The nub 20 can be inserted into the well of the base 16 in order to secure the cartridge 18 to the base 16. In some embodiments, the well includes a magnetic material adapted to magnetically engage with the nub 20 of the cartridge 18. Thus, the nub 20 is composed of a metallic or magnetic material so as to be able to magnetically engage with the well of the base 16. In other embodiments, the well comprises one or more teeth 25 therein, as shown in FIG. 2, wherein the teeth 25 help to secure the nub 20 within the well.

Referring now to FIG. 2, there is shown a view of an embodiment of the pet waste disposal apparatus having a telescopic shaft. In the illustrated embodiment, the elongated shaft 14 is telescopic so that the length of the shaft can be increased or decreased as desired by the user. The elongated shaft 14 comprises a plurality of tubular sections 30 having a decreasing cross sectional area, wherein the sections can be collapsed into one another or can be extended from one another so as to adjust the length thereof.

Each section 30 includes a locking mechanism 31 for maintaining the elongated shaft at a desired length. In the illustrated embodiment, the locking mechanism 31 comprises one or more holes that engage with protuberances. At least one of the plurality of sections 30 provides at least one hole and one protuberance disposed thereon, wherein the protuberance of a smaller sized section can engage with the hole of a larger sized section and becomes affixed therein as to lock the elongated shaft to a desired size for the user. In use, the user can manually grasp each section and adjust it to a desired length via the locking mechanism 31.

Referring now to FIG. 3, there is shown an overhead view of the cartridge of the pet waste disposal apparatus. The pet waste disposal apparatus comprises a removable cartridge 18. In the illustrated embodiment, the cartridge 18 comprises an octagonal shape, however, in alternate embodiments, the cartridge 18 comprises any of various other shapes or geometries. The cartridge 18 comprises a first side and a second side, wherein the first side provides a nub 20. The nub 20 comprises a cylindrical shape. The nub is constructed so as to fit within the interior volume of the well for removable securement thereto. When the cartridge 18 is secured to the base, the first side becomes substantially flush with the plate of the base.

The second side of the cartridge 18 comprises a plurality of tines 19 disposed thereon. The tines 19 extend substantially perpendicularly from the cartridge 18 and are intended to impale pet waste. The tines 19 are shown as having a conical shape, however, in alternate embodiments the tines 19 can resemble sharp pins or may have a triangular shape. The tines 19 are preferably evenly spaced on the cartridge 18. The tines 19 are preferably substantially the same shape and size so that the tines 19 can uniformly collect pet waste. The tines 19 may be arranged in a grid pattern on the cartridge 18 so that the tines 19 are uniformly distributed on the cartridge 18.

In operation, the user can place a disposable plastic bag over the base of the pet waste disposal apparatus. The bag which can be used is a standard plastic bag having a top and a bottom, an open end, a unitary wall and an interior volume. When the bag is placed over the base of the pet waste disposal apparatus, the base and portion of the shaft of the device is located within the interior volume of the bag, wherein the base of the device rests against the interior volume at bottom of the bag. The open end of the bag is then located nearer the first end of the shaft of the device.

The user can grasp the handle of the device and manually align the open end of the well of the base with the nub 20 of the cartridge 18 and press the well of the device over the open end of the nub 20, wherein the teeth of the well contacts the first side of the nub 20 causing friction and securing the nub 20 within the interior volume of the well. As such, the plastic bag remains over the base and also within the interior volume of the well as it becomes pushed within the interior volume of the well upon pushing the nub 20 within the interior volume of the well and is this removably contained and secured therein.

When assembled as described above, the user can then impale the pet waste via pushing the tines of the cartridge 18 onto the pet waste, wherein the pet waste thus contacts the second side of the cartridge 18 and remains impaled and adhered to the tines 19 of the cartridge 18. The user can then fold the disposable bag over the cartridge 18 such that the interior volume of the bag encloses the cartridge 18 and the pet waste therein. The user can proceed to grasp the open end of the bag and pull the bag away from the plate of the base thus detaching and removing the nub 20 of the cartridge 18 from the well of the base. Consequently, the pet waste and the cartridge are contained in the bag and the user can tie a knot in order to seal the open end of the bag to which the user can then dispose of the pet waste and cartridge 18 in a sanitary manner.

It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
